Abstract
The effects of stereotaxic injection of amyloid β-peptide (Aβ1−42) into rat brain to induce white matter damage have been studied. Administration of 1 nmol Aβ1−42 into corpus callosum resulted in considerable damage to axons as evidenced by the loss of neurofilament-immunoreactive (NF-ir) fibers 6 h and 3 and 7 days post-injection. Significant damage was also evident to myelin (using Luxol fast blue myelin staining) and oligodendrocytes (using CC1 immunocytochemistry); in the latter case marked caspase-3 immunoreactivity was evident in oligodendrocytes. Additionally, the numbers of GFAP-ir astrocytes and OX-42/OX-6-ir microglia were markedly increased following Aβ1−42 injection. These results suggest that Aβ plays an important pathophysiological role in white matter damage and that inflammatory responses may contribute to Aβ-induced demyelination and oligodendrocyte injury in corpus callosum. Loss of function of cells in corpus callosum could provide a potential new model for the study of white matter damage in Alzheimer's disease.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
